How to Add a Custom Internet Radio Station?
Method 1
1. Create a new text file named radio.txt in the root directory of the MicroSD (TF) card. The file must be encoded in UTF-8.
2. Open the text file and enter the radio station name and URL. The name and URL should be separated by a comma (,), and each station should be on a new line.
Example:
China National Radio, http://ngcdn001.cnr.cn/live/zgzs/index.m3u8
Music Radio, http://ngcdn003.cnr.cn/live/yyzs/index.m3u8
Method 2
Thanks to Reddit user "dough10" for this method:
Visit https://customradio.dough10.me and select the radio stations you want.
Click Download, and your browser will download a radio.txt file.
Copy the radio.txt file to the root directory of the MicroSD (TF) card.
If you already have existing stations in a radio.txt file, you can append the new content from the downloaded file to your original radio.txt.
